There is no common adjective formed from recipe. There might be an uncommon one listed in some dictionaries, but the OED has neither recipial nor recipital.

However, English allows us to use nouns as noun modifiers in many cases. Recipe ideas and recipe suggestions are both familiar phrases, but they mean ideas for recipes etc, which is not what you are talking about.

In fact, your recipe to your problems does not make sense to me: a recipe in its transferred sense is a set of steps to achieve something; that is different from a solution to a problem. You would have to say something like

Here are some suggestions which may give you a recipe for solving your problems.
